Application filed September 8, 1887. Serial No. 249,101. (X model.)

To all whom 21/; may concern:

Be it known that I, Gnonon H. GILBERT, a citizen of the United States, and a resident of Philadelphia, Pennsylvania, have invented certain Improvements in Oil, Gas, or Vapor Stoves, ofwhieh the following is a specification.

The main object of my invention is to con struct a safety-stove, using oil or gas as a fuel;

to and this object I attain in the manner hereinafter set forth, reference being had to the accompanying drawings, in which- Figure l is a transverse section, partly in elevation, showing my improved stove used :5 for a car-heater. Fig. 2 is a sectional view of the stove, showing the parts separated from each other. Fig. 3 is asectional plan view on the line 1 2, Fig. 2. Fig. 4 is an enlarged sectional view of the lower portion ofthe stove,

and Fig. 5 is a view of a modification of part of the invention.

The stove comprises upper and lower sections, A and B, the upper section having at the lower end a ring, a, which rests upon a ring, D, at the upper end of the lower section, but is not secured thereto, so that the two parts are readily separable from each other. The casing of the lower section of the stove comprises the ring D, a base'ring, (Z, a base plate, a, secured thereto, and inner and outer shells, ff, inclosing aspace, f, through which air can circulate, the outer shell being pro vided at top and bottom with perforations 0, so as to provide for such circulation of air in The lower section of the stovein the present instance oarries a fuel-block, D, which should be of porous and refractory material, and the baseplate 6 is provided with a pipe, 9, which ex- 0 tends beyond the casing of the stove, and is bent upward at the outer end, so that oil may be poured through said pipe for the purpose of saturating the block, the latter being mounted upon suitable rings or studs, 2', on the baseplate, in order that the oil may gain access to almost the entire area of the under sur face of the block and be readily absorbed thereby.

When the stove is used as a car-heater, as

shown in Fig. 1, the oilsupply pipe is pref- 5o erably carried to the outside of the car, so that the charging of the block can be effected without the necessity of carrying the oil inside the car.

Tubes m extend through the block D and through the baseplate e, so as to supply air to the upper surface of said block to mix with the vapors arising from the oil with which the lock is saturated, the mixture of air and vapor forming a combustible compound.

A short distance above the top of the block D is supported a slotted plate, a, and the mixture of air and vapor is effected in the space between this plate and the top of the block, the mixture ascending through the slots]? in the plate, the area of which'slots is governed by the adjustment of a damper-plate, 8, resting upon said platen. This damper-plate has an operating-rods, which passes down through the central tube, at, and is provided at the lower end with a handle, it, by the manipulation of which the damper-plate may be adjusted to regulate the area of the openings for the escape of the gaseous mixture of air and vapor from the block. 7

The ring a at the lower portion of the up per section, A, of the stove carries two screens,

a: or, which are some distance apart, and are of such fine gage that, while they will permit the upward passage of the gaseous mixture of air and vapor, they will eiiectually prevent any access of flame to the chamber beneath the screens. It will therefore be seen that the flame is confined to the combustionchamber above the screens; hence, if the upper sec tion of the stove is separated from the lower section, B, either by the overturning of the stove or from other cause, the flame will be extinguished by the cutting off of the supply of gaseous vapor therefrom, and the ignition of the oil in the fue1-block, or of the gaseous vapors arising from said block, will be prevented.

Although I have described and prefer to use a porous fuelblock in my improved stove, 5 said block may in some cases be dispensed with, the liquid fuel being contained in the chamber of the lower section, B, of the stove,

or gas may be stored in said chamber, the escape being regulated by the valve or damper s, and the gas then passing through the screens and being ignited above the same.

A plate having projecting tubes :0, as shown in Fig. 5, for instance, may, if desired, be'substituted for the screen as, the plate between the tubes being either perforated or plain; but such plate is more expensive than the screens and will warp and buckle more readily under the influence of heat; hence the use of the screens is preferred.

The provision of an air-jacket around the lower section of the stove prevents the excessive heating of the outer shell, which would belikely to occur in the absence of this airjacket, besides which the said jacket serves as an air heating and circulating device independent of the combustionchamber of the stove, a portion of the air in the construction shown in the drawings escaping from the easing into the room or apartment to be heated and another portion escaping into the space above the fuel-block, where it mixes with the gas arising from said block.

Above the upper screen w is supported a deflector-plate, P, which serves to direct the ignited gas toward the sides of the stove, where it is most available for heating purposes.

The main features of my invention may also be used in the construction of a lamp, the easing of the combustion-chamber in this case be ing of glass, mica, or other transparent material.

I claim as my invention 1. The combination of the lower section of the structure containing the fuel-chamber with the upper section resting upon but free to be separated from said lower section and containing the combustion-chamber, said upper section having in the lower portion a screen, whereby the downward passage of the flame from the combustion-chamber is prevented, all substantially as specified.

2. The combination of the'structure having the fuel-chamber in the lower portion and the combustion-chamber in the upper portion with upper and lower separated screens through which the ignitible vapor from the fuel passes before reaching the combustionchamber, all substantially as specified.

In testimony whereof I have signed my name to this specification in the presence of two sub scribing witnesses.
